There’s something called the “curse of the second-born child” that states that the child born second are typically a huge pain in the ass. Throughout the years this was a myth and only backed up with anecdotal evidence, but a new study reveals that second-born children are assholes who get into trouble way more than their siblings. According to Joseph Doyle, an MIT economist, the “second-born curse” is real and it will haunt parents for 18+ years.
